1 Introduction
Thank you for purchasing the 802.11g Turbo Wireless LAN USB Module. This USB Module is designed
to comply with IEEE 802.11g Wireless LAN standard. It enables any devices to operate wirelessly..
This module supports higher data throughput than the IEEE 802.11g standard (up to 54Mbps). It
supports specific ways to increase the data transfer rate at a time; compress the data and decrease the
waiting time to send the next data to the Routers or APs. This feature is called Turbo Mode. When the
module is connecting to the Routers or APs with the proprietary feature, the wireless network will be
more effective.
For WLAN security issues, this module supports 64/128-bit WEP data encryption that protects your
wireless network from eavesdropping. It also supports WPA (Wi-Fi Protected Access) feature that
combines IEEE 802.1x and TKIP (Temporal Key Integrity Protocol) technologies. Client users are
required to authorize before accessing to APs or AP Routers, and the data transmitted in the network is
encrypted/decrypted by a dynamically changed secret key. Furthermore, this module supports WPA2
function, WPA2 provides a stronger encryption mechanism through AES (Advanced Encryption
Standard), which is a requirement for some corporate and government users.
When you use the devices with services such as Voice over Internet Protocol (VoIP) phones,
televisions and MP3 players, how can you speed up the audio, video and voice data to pass through
the wireless network? IEEE 802.11e Quality of Service (QoS) (The Wi-Fi Alliance defined WMM as a
profile of the IEEE 802.11e) extensions for 802.11 networks will help to define the priorities of the data
traffics by the data categories to provide enhanced multimedia support. This module supports the
advanced technology for sure.
This module is cost-effective, together with the versatile features; it is the best solution for you to build
your wireless network.

active mode.
PSM (Power Saving Mode) – Enable the module in the power
saving mode when it is idle.
12
Parameter
Description
Network Type
Infrastructure – This operation mode requires the presence of an
802.11 Access Point. All communication is done via the Access
Point or Router.
Ad-Hoc – Select this mode if you want to connect to another
wireless stations in the Wireless LAN network without through an
Access Point or Router.
TX Power
If you want to lower the transmit power of the module for saving the
power of the system, you can select the lower percentages from the
list. The lower power will cause the lower signal strength and the
coverage range.
Preamble
The preamble defines the length of the CRC block for
communication among wireless devices. This option is only active
in the Ad Hoc network.
There are two modes including Auto and Long Preamble. If
“Auto“ mode is selected, the module will auto switch the preamble
mode depending on the wireless devices the module is connecting
to.
RTS Threshold
Minimum packet size required for an RTS (Request To Send). For
packets smaller than this threshold, an RTS is not sent and the
packet is transmitted directly to the wireless network. Select a
setting within a range of 0 to 2347 bytes. Minor change is
recommended.
Fragment Threshold
The value defines the maximum size of packets; any packet size
larger than the value will be fragmented. If you have decreased this
value and experience high packet error rates, you can increase it
again, but it will likely decrease overall network performance. Select
a setting within a range of 256 to 2346 bytes. Minor change is
recommended.
Channel
This setting is only available for Ad Hoc mode. Select the number of
the radio channel used for the networking. The channel setting
should be the same with the network you are connecting to.
13
3.2.1.2
Authentication and Security
Parameter
Description
Authentication Type
This setting has to be consistent with the wireless networks that
the module intends to connect.
Open – No authentication is needed among the wireless network.
Shared – Only wireless devices using a shared key (WEP Key
identified) are allowed to connecting each other.
LEAP – LEAP is a pre-EAP, Cisco-proprietary protocol, with many
of the features of EAP protocols. Cisco controls the ability of other
vendors to implement this protocol, so it should be selected for
use only when limited vendor choice for client, access-point, and
server products is not a concern. When you have set up LEAP
authentication, you have to enter the user name and password of
your computer.
WPA – WPA provides a scheme of mutual authentication using
either IEEE 802.1x/Extensible Authentication Protocol (EAP)
authentication or pre-shared key (PSK) technology. It provides a
high level of assurance to enterprises, small businesses and
home users that data will remain protected and that only
authorized users may access their networks. For enterprises that
have already deployed IEEE 802.1x authentication, WPA offers
the advantage of leveraging existing authentication databases
and infrastructure.
14
Parameter
Description
WPA-PSK – It is a special mode designed for home and small
business users who do not have access to network authentication
servers. In this mode, known as Pre-Shared Key, the user
manually enters the starting password in their access point or
gateway, as well as in each wireless station in the network.
WPA-PSK takes over automatically from that point, keeping
unauthorized users that don't have the matching password from
joining the network, while encrypting the data traveling between
authorized devices.
WPA2 – Like WPA, WPA2 supports IEEE 802.1x/EAP
authentication or PSK technology. It also includes a new
advanced encryption mechanism using the Advanced Encryption
Standard (AES). AES is required to the corporate user or
government users. The difference between WPA and WPA2 is that
WPA2 provides data encryption via the AES. In contrast, WPA
uses Temporal Key Integrity Protocol (TKIP).
WPA2-PSK – WPA2-PSK is also for home and small business.
The difference between WPA-PSK and WPA2-PSK is that
WPA2-PSK provides data encryption via the AES. In contrast,
WPA-PSK uses Temporal Key Integrity Protocol (TKIP).
WPA-NONE – WPA-NONE is defined for Ad hoc mode and
behaves like WPA-PSK (WPA-PSK is only defined for
infrastructure mode). The user manually enters the Pre-Shared
Key in each wireless station in the network and WPA-NONE
controls unauthorized users that don't have the matching
Pre-Shared Key from joining the network and also encrypts the
data traveling between authorized devices.
802.1x Setting
When you have set the Authentication Type to Open, Shared,
WPA or WPA2, you can also enable IEEE 802.1x setting to use
the authentication server or certification server to authenticate
client users.
Encryption Mode
None – Disable the encryption mode.
WEP – Enable the WEP Data Encryption. When the item is
selected, you have to continue setting the WEP Encryption keys.
TKIP – TKIP (Temporal Key Integrity Protocol) changes the
temporal key every 10,000 packets (a packet is a kind of message
transmitted over a network.) This ensures much greater security
than the standard WEP security.
15
Parameter
Description
AES – AES has been developed to ensure the highest degree of
security and authenticity for digital information and it is the most
advanced solution defined by IEEE 802.11i for the security in the
wireless network.
Note: All devices in the network should use the same encryption
method to ensure the communication.
WPA Pre-Shared Key
The WPA-PSK key can be from 8 to 64 characters and can be
letters or numbers. This same key must be used on all of the
wireless stations in the network.
WEP Key
(Key1 ~ Key4)
The WEP keys are used to encrypt data transmitted in the
wireless network. There are two types of key length: 64-bit and
128-bit. Select the default encryption key from Key 1 to Key 4 by
selected the radio button.
Fill the text box by following the rules below.
64-bit – Input 10-digit Hex values (in the “A-F”, “a-f” and “0-9”
range) or 5-digit ASCII characters (including “a-z” and “0-9”) as
the encryption keys. For example: “0123456aef“ or “test1”.
128-bit – Input 26-digit Hex values (in the “A-F”, “a-f” and “0-9”
range) or 13-digit ASCII characters (including “a-z” and “0-9”) as
the encryption keys. For example:
“01234567890123456789abcdef“ or “administrator”.
16
The IEEE 802.1X specification describes a protocol that can be used for authenticating both clients and
servers on a network. The authentication algorithms and methods are those provided by the Extensible
Authentication Protocol (EAP), a method of authentication that has been in use for a number of years
on networks that provide Point-to-Point Protocol (PPP) support as many internet service providers and
enterprises do.
When an AP acting as an authenticator detects a wireless station on the LAN, it sends an EAP-Request
for the user's identity to the device. (EAP, or the Extensible Authentication Protocol, is an authentication
protocol that runs before network layer protocols transmit data over the link.) In turn, the device
responds with its identity, and the AP relays this identity to an authentication server, which is typically
an external RADIUS server.

3.2.1.3
802.1x Setting-Certification
Parameter
Description
Authentication Type
The EAP authentication protocols this module has supported are
included as follows. This setting has to be consistent with the
wireless APs or Routers that the module intends to connect.
PEAP &TTLS – PEAP and TTLS are similar and easier than TLS
in that they specify a stand-alone authentication protocol be used
within an encrypted tunnel. TTLS supports any protocol within its
tunnel, including CHAP, MS-CHAP, MS-CHAPv2, PAP and
EAP-MD5. PEAP specifies that an EAP-compliant authentication
protocol must be used; this module supports EAP-MSCHAP v2,
EAP-TLS/Smart Card and Generic Token Card. The client
certificate is optional required for the authentication.
TLS/Smart Card –TLS is the most secure of the EAP protocols
but not easy to use. It requires that digital certificates be
exchanged in the authentication phase. The server presents a
certificate to the client. After validating the server’s certificate, the
client presents a client certificate to the server for validation.
Session Resumption
There are “Disabled”, “Reauthentication”, “Roaming”, “SameSsid”
and “Always” selections for you to choose whether to recovery the
session in different status.
Password
Enter the password as the identity for the server.
Use Client Certificate
A client certificate is required for TLS, and is optional for TTLS and
PEAP. This forces a client certificate to be selected from the
appropriate Windows Certificate Store and made available to the
RADIUS server for certification.
Tunneled Authentication
Protocol
When the authentication type is PEAP or TTLS, select a protocol
to be used to build the encrypted tunnel.
Identity
This is the protected user EAP Identity used for authentication.
The identity specified may contain up to 63 ASCII characters, is
case sensitive and takes the form of a Network Access Identifier,
consisting of @. The
user’s home realm is optional and indicates the routing domain.
Password
The password used for authentication. It may contain up to 63
ASCII characters and is case sensitive.
18
3.2.1.4
802.1x Setting-CA Server
Parameter
Description
Use Certificate Chain
When the EAP authentication type such as TLS, TTLS or PEAP is
selected and required a certification to tell the client what server
credentials to accept from the authentication server in order to
verify the server, you have to enable this function.
Certificate Issuer
Choose the server from the list to issue the certificate. If “Any
Trusted CA” is selected, any CA included in the list (provided by
the Microsoft Certificate Store) is permitted.
Allow Intermediate Certificates
A server designates an issuer as a trusted root authority by
placing the issuer's self-signed certificate, which contains the
issuer's public key, into the trusted root certification authority
certificate store of the host computer. Intermediate or subordinate
certification authorities are trusted only if they have a valid
certification path from a trusted root certification authority.
Server Name
Enter the authentication server name.
Server name must match exactly
When selected, the server name must match exactly the server
name found on the certificate.
Domain name must end in
specified name
When selected, the server name field identifies a domain. The
certificate must use a server name belonging to this domain or to
one of its sub-domains (e.g. zeelans.com, where the server is
blueberry.zeelans.com) but it may be any name used in the
certificate name field.

4 Glossary
This chapter provides solutions to problems usually encountered during the installation and operation
of the module.
1. What is the IEEE 802.11g standard?
802.11g is the new IEEE standard for high-speed wireless LAN communications that provides for
up to 54 Mbps data rate in the 2.4 GHz band. 802.11g is quickly becoming the next mainstream
wireless LAN technology for the home, office and public networks.
802.11g defines the use of the same OFDM modulation technique specified in IEEE 802.11a for
the 5 GHz frequency band and applies it in the same 2.4 GHz frequency band as IEEE 802.11b.
The 802.11g standard requires backward compatibility with 802.11b.
The standard specifically calls for:
A. A new physical layer for the 802.11 Medium Access Control (MAC) in the 2.4 GHz frequency
band, known as the extended rate PHY (ERP). The ERP adds OFDM as a mandatory new
coding scheme for 6, 12 and 24 Mbps (mandatory speeds), and 18, 36, 48 and 54 Mbps
(optional speeds). The ERP includes the modulation schemes found in 802.11b including
CCK for 11 and 5.5 Mbps and Barker code modulation for 2 and 1 Mbps.
B. A protection mechanism called RTS/CTS that governs how 802.11g devices and 802.11b
devices interoperate.
2. What is the IEEE 802.11b standard？
The IEEE 802.11b Wireless LAN standard subcommittee, which formulates the standard for the
industry. The objective is to enable wireless LAN hardware from different manufactures to
communicate.
3. What does IEEE 802.11 feature support？
The product supports the following IEEE 802.11 functions:
CSMA/CA plus Acknowledge Protocol
Multi-Channel Roaming
Automatic Rate Selection
RTS/CTS Feature
Fragmentation
Power Management
4. What is Ad-hoc？
An Ad-hoc integrated wireless LAN is a group of computers, each has a Wireless LAN module,
Connected as an independent wireless LAN. Ad hoc wireless LAN is applicable at a
departmental scale for a branch or SOHO operation.
5. What is Infrastructure？
An integrated wireless and wireless and wired LAN is called an Infrastructure configuration.
Infrastructure is applicable to enterprise scale for wireless access to central database, or
wireless application for mobile workers.
37
6. What is BSS ID？
A specific Ad hoc LAN is called a Basic Service Set (BSS). Computers in a BSS must be
configured with the same BSS ID.
7. What is WEP？
WEP is Wired Equivalent Privacy, a data privacy mechanism based on a 40 bit shared key
algorithm, as described in the IEEE 802 .11 standard.
8. What is TKIP?
TKIP is a quick-fix method to quickly overcome the inherent weaknesses in WEP security,
especially the reuse of encryption keys. TKIP is involved in the IEEE 802.11i WLAN security
standard, and the specification might be officially released by early 2003.
9. What is AES?
AES (Advanced Encryption Standard), a chip-based security, has been developed to ensure the
highest degree of security and authenticity for digital information, wherever and however
communicated or stored, while making more efficient use of hardware and/or software than
previous encryption standards. It is also included in IEEE 802.11i standard. Compare with AES,
TKIP is a temporary protocol for replacing WEP security until manufacturers implement AES at
the hardware level.
10. Can Wireless products support printer sharing？
Wireless products perform the same function as LAN products. Therefore, Wireless products can
work with Netware, Windows 2000, or other LAN operating systems to support printer or file
sharing.
11. Would the information be intercepted while transmitting on air？
WLAN features two-fold protection in security. On the hardware side, as with Direct Sequence
Spread Spectrum technology, it has the inherent security feature of scrambling. On the software
side, WLAN series offer the encryption function (WEP) to enhance security and Access Control.
Users can set it up depending upon their needs.
12. What is DSSS？What is FHSS？And what are their differences？
Frequency-hopping spread-spectrum (FHSS) uses a narrowband carrier that changes frequency
in a pattern that is known to both transmitter and receiver. Properly synchronized, the net effect
is to maintain a single logical channel. To an unintended receiver, FHSS appears to be
short-duration impulse noise. Direct-sequence spread-spectrum (DSSS) generates a redundant
bit pattern for each bit to be transmitted. This bit pattern is called a chip (or chipping code). The
longer the chip is, the greater the probability that the original data can be recovered. Even if one
or more bits in the chip are damaged during transmission, statistical techniques embedded in the
radio can recover the original data without-the need for retransmission. To an unintended
receiver, DSSS appears as low power wideband noise and is rejected (ignored) by most
narrowband receivers.
38
13. What is Spread Spectrum？
Spread Spectrum technology is a wideband radio frequency technique developed by the military
for use in reliable, secure, mission-critical communication systems. It is designed to trade off
bandwidth efficiency for reliability, integrity, and security. In other words, more bandwidth is
consumed than in the case of narrowband transmission, but the trade off produces a signal that
is, in effect, louder and thus easier to detect, provided that the receiver knows the parameters of
the spread-spectrum signal being broadcast. If a receiver is not tuned to the right frequency, a
spread –spectrum signal looks like background noise. There are two main alternatives, Direct
Sequence Spread Spectrum (DSSS) and Frequency Hopping Spread Spectrum (FHSS).
14. What is WMM？
Wi-Fi Multimedia (WMM), a group of features for wireless networks that improve the user
experience for audio, video and voice applications. WMM is based on a subset of the IEEE
802.11e WLAN QoS draft standard. WMM adds prioritized capabilities to Wi-Fi networks and
optimizes their performance when multiple concurring applications, each with different latency
and throughput requirements, compete for network resources. By using WMM, end-user
satisfaction is maintained in a wider variety of environments and traffic conditions. WMM makes it
possible for home network users and enterprise network managers to decide which data streams
are most important and assign them a higher traffic priority.
15. What is WMM Power Save？
WMM Power Save is a set of features for Wi-Fi networks that increase the efficiency and
flexibility of data transmission in order to conserve power. WMM Power Save has been optimized
for mobile devices running latency-sensitive applications such as voice, audio, or video, but can
benefit any Wi-Fi device. WMM Power Save uses mechanisms included in the IEEE 802.11e
standard and is an enhancement of IEEE 802.11 legacy power save. With WMM Power Save,
the same amount of data can be transmitted in a shorter time while allowing the Wi-Fi device to
remain longer in a low-power “dozing” state.
